BOILER.

SPECIFICATION forming part of Letters Patent No. 233,582, dated October 19, 1880.

Application led September 8, 1880. (No model.)

To all whom t may concern Be it known that I, AUsBER'r H. WAGNER, ot Chica-go, in the county of Cook and State ot" Illinois, have invented certain new and uscful Improvements in Steam-Boilers, of which the following` is a specification.

My invention mainly relates to im provenients in upright tubular boilers or steam-generators, particularly that type of such class in which the generator is made in two parts, one section over the other.-

My invention involves improvements in various parts of the mechanism, hereinafter tirst fully described preparatory to specific designation ot' the subject-matter claimed.

In the accompanying drawings my improvements are represented in connection with parts of an engine and a traction-wagon especially adapted to be operated thereby. Such parts constitute the subject-matterot another application, my present invention being contined to the boiler improvements.

Figure l is a plan or top view with a part of the top ot' the casing or hot-airjacket broken away. Fig. 2 is a view, partly in side elevation and partly in vertical longitudinal section on the line 2 2 of Fig. 1. Figis a view, partly in rear elevation and partly in vertical transverse section on the lines 3 3 ot' Figs. l and 4. Fig. 4 is a transverse horizontal section on the line 4 et of Fig. 3. Fig. 5 is a view in perspective, with some parts broken or in section, ot' the generator proper and its appurtenances or immediate connections. Fig. 6 is a front elevation otl the engine properthat is to say, the cylinder, crank-shaft, supporting-columns, &c.

A vertical sectional tubular generator or boiler,A A ,is suitably supported and inclosed in a shell or casing, B, of a size sufticiently larger than the boiler to leave a space between the outside of the boiler and inside of the shell, constituting a hot-air space, B. The iiues b and b of the lower or main section, A, and upper or top deck-section, A', of the boiler, respectively, are arranged in coinciding vertical planes-that is to say, each flue b of the upper section, A', ot' the boiler is directly over or in line with its corresponding ue b of the main section A.

A space, B2, separates the two sections and constitutes a ue chamber, into which the smoke or products of combustion passing up the tlues b from the furnace or ire-boxC pass on the way to the hot-air space or jacket-chamber B. y

The upper section ofthe boiler is heated by radiation, by impingemcnt of the flames, and by the waste products ot' combustion, as will readily be understood.

The t'uel is supplied to the furnace by a central feeding cylinder or magazine, C. Hard or softcoal or wood maybe used as fuel.

The smokeistack C2 communicates with the liet-air space orjacltet-chamber at its bottom only. (See Fig. 5.)

A vertical smoke-conducting chamber, D,-is formed between two suitably secured vertical partitions, d d. These division-plates d d terminate a little above the bottom of the hot-air chamber orjacket-space B and extend upward to the top ofthe boiler-section A. The space B2 is also closed between these plates in any simple way.

A single sheet of metal, bent at its edges to form the partitions d d', might be made to shut oft' communication between the chamber D and the fine-space B2 in an obvious way.'

The ianged base D ofthe hot-air casing or jacket-shell B serves to secure it to a suitable foundation. Four screw-bolts, d, in this instance serve to removably attach the shell to the water-tank body D2 ofthe traction-vehicle.

The upper and lower sections of the gener ator are connected in suitable way. One or more pipes leading from or near the top of the section A to or near the bottom of the boilersection A would answer, and steam passes to the steam-chest E by a pipe leading from the upper section, as will readily be understood without detailed description and illustration.

The boiler is, ot course, to be supplied with water by a pump in proper way.

The fuel-magazine or fuel-cylinder is provided with a removable cover, c, at top, and terminates at its discharge end in a daring serrated outlet a little below the level of the crown-sheet or lower ilue-sheet ot' the boiler. This magazine extends through large central openings or tubes in the two sections ot' the boiler.

The flues b' extend through the top section, A', of the boiler, and are adapted to be closed or opened at top by a perforated plate or register-disk, F, oscillating about the magazinetube C'. The openings f in this register, when it is properly adjusted, coincide with the fines b' or openings through the top flue-sheet of the section A', as will readily be understood. A slot, f', and its pin serve to limitthe movement of the perforated disk F, as usual in registers.

rlo facilitate the cleaning of the flues b and b', and at the same time render unnecessary the exposure or opening at top of all the ilues by the register F, a supplementary segmental cover or half-disk, E', is mounted to oscillate about the fuel-feeding cylinder on top of the register. When the register is adjusted to expose the tlues it will be seen that the imperforate segmental plate resting on the register will cover some of the register-openings and consequently keep closed those of the lines which coincide with them while leaving open the remainder for cleaning` by a suitable device inserted from above, and this without stopping the engine or materially interfering with the lire, draft, Ste. rIhe lines may thus be exposed snccessivel y in seriessay half at a time-for cleaning. At other times all may be kept closed.

It will be seen that by the employment of the fuel-magazine the engine may be run for a long time at one tiring up, and that by utilizin g to the utmost the heat from the products of combustion, even while passing along the vertical chamber or smoke-conducting passage D to the outlet or smoke-stack, the fullest benefits from a given expenditure of fuel are attained.

In view of the prior state of the art, I do not broadly cla-ini a boiler having a hot-air jacket, nor the division of the fines or arrangement of them in two sections, one above the other, so as to coincide; neither do I unqualiiedly claim the combination of such features, but concerning these and other part-s confine my claims to subject-matter, essentially as below designated, distinguishing my improvements from prior inventions.

I claim as of my own inventionl. The combination, substantially as hereinbefore set forth, of the upright tubular sectional boiler, having the flue-chamber or liorizontal space between the two sections, the shell or casing, with the hot-air space or jacketchamber between it and the boiler, and the smoke-conducting chamber, by which the products ot' combustion pass from the bottom of said jacket-chamber to the outlet or smokestack.

2. The combination, substantially as hereinbefore set forth, of the upper and lower sections of the boiler, each provided with a series of flues, the upper series of flues coinciding with or arranged vertically over the fines of the lower series and separated therefrom by the flue chamber or space between the two sections of the boiler and the register-plate, by means of which the lues may be closed or eX- posed for cleaning throughout from above, as described.

3. The combination of the tubular upright boiler, the shell or casing, the register-plate, and the segmental plate, substantially as and for the purpose hereinbefore set forth.

4. The combination, substantially as hereinbefore set forth, of the shell or casing, the boiler composed of the upper and lower sections, having coinciding lines, and the horizontal space or flue-chamber between them, and the fuel-feeding cylinder passing centrally through said sections and flue-chamber.

5. rIhe combination, in a steam-generator, of the hot-airjacket shell or casing, the upper and lower sections, A A, having the coinciding tlues and the space between them, the central fuel-feeding cylinder, the register-plate oscillating about said cylinder, and the segmental plate, also oscillating about the feedingcylinder, substantially as and for the purpose set forth.

6. The combination of the shell or easin g B, the tubular boiler-sections A A', the line-space B2, the vertical partitions d cl',between which the flue-space is closed, and the slnoke-stack, substantially as and for the purpose hereinbefore set forth.

In testimony whereof I have hereunto subroo Witnesses:

F. H. SMITH, CHARLES A. Roe-Ens.
